A signal shielding and transmitting case with a length-adjustable antenna comprises a signal shielding case 100, a remote control part 200, a PCB 300, a control line 400, a signal transmitting antenna 500, an antenna driving part 600 and a power transmission part 700.

The remote control part 200 is fixedly connected to one side of the signal shielding case 100, the PCB 300 is arranged in the signal shielding case 100, the antenna driving part 600 is arranged on one side of the PCB 300, the power transmission part 700 is arranged in the remote control part 200, the control line 400 penetrates through the antenna driving part 600 and is fixedly connected to the signal transmitting antenna 500, the remote control part 200 drives the power transmission part 700 to rotate, then the power transmission part 700 drives the antenna driving part 600 to rotate, and the antenna driving part 600 controls the control line 400 to move to enable the signal transmitting antenna 500 to stretch out or retreat into the signal shielding case 100.

Wherein, the signal shielding case 100 can be applied to remote control keys, navigator, positioners or other products to shield electromagnetic signals; the PCB 300 is installed in the signal shielding case 100, and the signal shielding case 100 has a shielding effect on the signal transmitting antenna 500, such that the signal transmitting antenna 500 will not send a control signal to external equipment that is to be remotely controlled unless it is stretched out of the signal shielding case 100 by users, and misoperation can be effectively avoided.

Moreover, when the signal transmitting antenna 500 stretches out of the signal shielding case 100 by different lengths, the intensities of signals transmitted by the signal transmitting antenna 500 will be different, such that the length of the signal transmitting antenna 500 stretching out of the signal shielding case 100 can be controlled by users according to the distance to the external equipment to be controlled to make operations more intelligent.

The signal transmitting antenna 500 is electrically connected to the PCB 300, so that the signal transmitting antenna 500 can generate signals for controlling the external equipment.

Furthermore, when using the signal shielding and transmitting case with a length-adjustable antenna, users control the remote control part 200 to slide at first to drive the power transmission part 700 to rotate, then the power transmission part 700 drives the antenna driving part 600 to move, then the control line 400 is driven by the antenna driving part 600 to move, and the signal transmitting antenna 500 is driven by the control line 400 to stretch out or retreat into the signal shielding case 100. In this way, the signal transmitting antenna 500 can be freely controlled to stretch out of the signal shielding case 100.

Referring to FIG. 6 again, in this embodiment, the power transmission part 700 comprises a first gear 710, a connector 720 and a second gear 730, wherein the first gear 710 and the second gear 730 are sequentially disposed around the connector 720, the first gear 710 abuts against the remote control part 200, and the second gear 730 abuts against the antenna driving part 600.

Wherein, when users slide the remote control part 200, the first gear 710 is driven to rotate at first to drive the connector 720 to rotate synchronously; when the connector 720 rotates, the second gear 730 rotates along with the connector 720 to drive the antenna driving part 600 to rotate, then the antenna driving part 600 drives the control line 400 to rotate, and finally, the control line 400 drives the signal transmitting antenna 500 to move.

In this embodiment, diameter ratio of the first gear 710 and the second gear 730 is 1:1, 1:1.1, 1:1.2, 1:1.3, 1:1.4 or 1:1.5.

Wherein, users can set the diameter ratio of the first gear 710 and the second gear 730 according to specific service environments. By changing the diameter ratio of the first gear 710 and the second gear 730, when the users control the remote control part 200 to drive the first gear 710 to rotate, the signal transmitting antenna 500 will move by different distances due to different diameter ratios of the first gear 710 and the second gear 730 even if the users control the remote control part 200 to slide by the same distance. It should be noted that the invention has no limitation on the specific diameter ratio of the first gear 710 and the second gear 730, that is, the diameter ratio of the first gear 710 and the second gear 720 can be set freely.

Referring to FIG. 3 again, in this embodiment, a protector 711 is arranged on the outer side of the first gear 710 and is formed with a notch 712, and one side of the first gear 710 stretches out of the notch 712 to abut against the remote control part 200.

Wherein, the protector 711 can reduce the contact area between the first gear 710 and the remote control part 200 and can protect the first gear 710, so that the service life of the first gear 710 is prolonged.

That is, in this embodiment, the remote control part 200 only contacts with the portion, stretching out of the notch 712, of the first gear 710.

In this embodiment, the remote control part 200 comprises a fixing part 210 and a sliding part 220, wherein the fixing part 210 is fixedly connected to the upper side of the signal shielding case 100, the sliding part 220 is slidably connected into the fixing part 210, and a first driving strip 221 is fixedly connected to a side, facing the interior of the fixing part 210, of the sliding part 220 and abuts against the power transmission part 700.

Wherein, when users need to control the length of the signal transmission antenna 500 stretching out of the signal shielding case 100, the position of the fixing part 210 is fixed, the sliding part 220 slides in the fixing part 210 to drive the first driving strip 221 to slide, and then the first driving strip 221 drives the first gear 710 in the power transmission part 700 to rotate. In this way, the first gear 710 is driven, and the first driving strip 221 and the first gear 710 may be engaged.

In this embodiment, anti-skid protrusions 222 are arranged on a side, away from the fixing part 210, of the sliding part 220.

Wherein, the anti-skid 222 protrusions are arranged regularly or irregularly and can enlarge the contact area between users and the sliding part 220, so that the users can adjust the sliding part 220 easily.

In this embodiment, a first fixing cavity 610 and a second fixing cavity 620 are formed in one side of the antenna driving part 600, and a portion, stretching into the antenna driving part 600, of the control line 400 sequentially penetrates through the first fixing cavity 610 and the second fixing cavity 620.

Wherein, the portion, stretching into the antenna driving part 600, of the control line 400 can be clamped and fixed by the first fixing cavity 610 and the second fixing cavity 620, so that when the position of the antenna driving part 600 changes, the control line 400 can better move along with the antenna driving part 600. Of course, the purpose of clamping the control line 400 can also be realized if only one of the first fixing cavity 610 and the second fixing cavity 620 is configured.

In this embodiment, a limiting pole 310 for limiting the control line 400 is fixedly connected to the PCB 300, a limiting sleeve 320 for limiting the moving track of the control line 400 is disposed around the limiting pole 310, and the control line 400 slides in the limiting sleeve 320 to control the movement of the signal transmitting line 500.

Wherein, the limiting sleeve 320 can limit the control line 400 to prevent it from being out of order in the signal shielding case 100, and the limiting pole 310 is fixedly connected to the PCB 300 and is electrically connected to the PCB 300. When users controls the signal transmitting antenna 500 to stretch out or retreat into the signal shielding case 100, the control line moves in order under the effect of the limiting sleeve 320.

In this embodiment, the signal shielding case 100 comprises an upper shielding case 110 and a lower shielding case 120 which are detachably connected, and the upper shielding case 110 and the lower shielding case 120 are both electroplated components.

Wherein, the upper shielding case 110 and the lower shielding case 120 are detachably connected, so that the internal structures of the upper shielding case 110 and the lower shielding case 120 can be changed and maintained in time.

Moreover, the upper shielding case 110 and the lower shielding case 120 are both electroplated, so that an electromagnetic shielding effect is realized through the cooperation of the upper shielding case 110 and the lower shielding case 120.

In this embodiment, a groove part 130 is fixedly connected to the inner wall of the lower shielding case 120; when the upper shielding case 110 is assembled in the lower shielding case 120, the periphery of the upper shielding case 110 exactly abuts against the groove part 130, that is, a boss matched with the groove part 130 is formed on the periphery of the upper shielding case 110, so that the upper shielding case 110 can be exactly connected into the groove part 130, and the electromagnetic shielding effect of the upper shielding case 110 and the lower shielding case 120 is improved.

Wherein, when the periphery of the upper shielding case 110 abuts against the groove part 130, the overall electromagnetic shielding effect on signals of the signal shielding case 100 is improved. In another embodiment, no groove part 130 is arranged in the lower shielding case 120, and when the upper shielding case 110 stretches into the lower shielding case 120 deeply enough, the electromagnetic shielding effect can still be realized.

In this embodiment, a fixing plate 800 is fixedly connected to one side of the signal shielding case 100, a protective sleeve 820 is detachably connected to the outer side of the fixing plate 800, multiple limiting grooves 810 are formed in the fixing plate 800, two symmetrical limiting blocks 830 for locking the protective sleeve 820 are slidably arranged on a side, away from the signal shielding case 100, of the fixing plate 800 and are connected through a spring 840, and the limiting blocks 830 slide in limiting grooves 810 to lock or unlock the protective sleeve 820.

Wherein, the fixing plate 800 can improve the stability of the signal shielding and transmitting case, and the protective sleeve 820 can be disposed around one side of the signal shielding case 100 to protect the signal transmitting antenna 500 and can prevent dust to some certain extent to prolong the service life of the signal shielding and transmitting case.

Moreover, the limiting blocks 830 can lock the protective sleeve 820; when the two limiting blocks 830 squeeze each other, the protective sleeve 820 will no longer be locked by the limiting blocks 830 and can be detached freely; when a force applied to the limiting blocks 830 disappears, the limiting blocks 830 return to initial positions under the elastic effect of the spring 840.

The signal shielding and transmitting case with a length-adjustable antenna comprises the signal shielding case 100, the remote control part 200, the PCB 300, the control line 400, the signal transmitting antenna 500, the antenna driving part 600 and the power transmission part 700, wherein the remote control part 200 is fixedly connected to one side of the signal shielding case 100, the PCB 300 is arranged in the signal shielding case 100, the antenna driving part 600 is arranged on one side of the PCB 300, the power transmission part 700 is arranged in the remote control part 200, the control line 400 penetrates through the antenna driving part 600 and is fixedly connected to the signal transmitting antenna 500, the remote control part 200 drives the power transmission part 700 to rotate to drive the antenna driving part 600 to rotate, and then the antenna driving part 600 controls the control line 400 to move to enable the signal transmitting antenna 500 to stretch out or retreat into the signal shielding case 100, wherein the remote control part 200 can control the control line 400 based on the gear lever principle, such that the length of the signal transmitting antenna 500 stretching out of the signal shielding case 100 can be controlled to allow users to adjust the intensity of signals transmitted by the signal transmitting antenna 500 freely; moreover, different diameter ratios can be set for the power transmission part 700 to make the signal shielding and transmitting case more easy and convenient to adjust, and remote keys can be prevented from being misoperated or getting lost.
